Description
【請求項６】
請求項４に記載の強誘電性液晶混合物を含有する、強誘電性スイッチングおよび／または表示デバイス。
6.
A ferroelectric switching and / or display device comprising the ferroelectric liquid crystal mixture according to claim 4.
【請求項７】
アクティブマトリックス素子を備えており、また液晶層が単安定性モノドメインを形成している、請求項６に記載の強誘電性スイッチングおよび／または表示デバイス。
7.
7. The ferroelectric switching and / or display device according to claim 6, comprising an active matrix element and wherein the liquid crystal layer forms a monostable monodomain.
ネマティックおよびコレステリック液晶に加えて、最近、光学活性の傾斜配向されたスメクティック（強誘電性）液晶が市販表示デバイスに使用されている。
クラーク(Clark)およびラガーウォル(Lagerwall)は、非常に薄いセルで強誘電性液晶（ＦＬＣ）を使用すると、慣用のＴＮ（「ねじれネマティック」）セルに比較して、１０００倍まで迅速な応答時間を有する光電気スイッチング素子(switching element)または表示素子が得られることを証明することができた（例えば、EP-A 0032362参照）。このおよびその他の好ましい性質、例えば双安定スイッチングの可能性およびコントラストが視野角からほとんど独立しているという事実によって、ＦＬＣは基本的に、コンピューターディスプレイなどの用途分野に格別に適している。
In addition to nematic and cholesteric liquid crystals, recently, optically active, tilt-aligned smectic (ferroelectric) liquid crystals have been used in commercial display devices.
Clark and Lagerwall have shown that the use of ferroelectric liquid crystals (FLC) in very thin cells can provide up to 1000 times faster response times compared to conventional TN ("twisted nematic") cells. It was possible to prove that an opto-electrical switching element or a display element was obtained (see, for example, EP-A 0032362). Due to this and other favorable properties, such as the possibility of bistable switching and the fact that the contrast is almost independent of the viewing angle, FLCs are basically particularly suitable for applications such as computer displays.
本発明はさらにまた、式（Ｉ）で表わされる化合物を液晶混合物、好ましくはスメクティックおよびネマティック液晶混合物、特に好ましくはカイラルスメクティック（強誘電性）液晶混合物に使用することに関する。反転モードで動作するか、またはアクティブマトリックス素子を備えたディスプレイで動作する、強誘電性液晶混合物における使用は、特に好適である。
カイラルスメクティック液晶層が、単安定性モノドメインを形成するアクティブマトリックスＬＣＤ用の混合物における使用は、非常に特に好ましい。
The invention furthermore relates to the use of the compounds of the formula (I) in liquid-crystal mixtures, preferably in smectic and nematic liquid-crystal mixtures, particularly preferably in chiral smectic (ferroelectric) liquid-crystal mixtures. Use in ferroelectric liquid crystal mixtures, which operate in the inversion mode or in displays with active matrix elements, is particularly preferred.
Chiral smectic liquid crystal layer is used in mixtures for active matrix LCD which forms a monostable monodomain is very particularly preferred.
本発明による式（Ｉ）で表わされる化合物を含有する液晶混合物の追加の成分は、好ましくはスメクティックおよび／またはネマティックおよび／またはコレステリック相を有する公知化合物から選択される。この場合に適当な追加の混合物成分は、特に国際特許出願 PCT/EP96/03154およびDE-A 19748432に挙げられており、これらの刊行物の記載を、引用してここに組み入れる。
本発明による混合物はまた、電気光学素子または完全光学素子、例えば表示素子、スイッチング素子、光モジュレーター、画像処理および／または信号処理用素もしくは一般に非線型光学部品の領域で使用することができる。
The additional components of the liquid-crystal mixtures containing the compounds of the formula (I) according to the invention are preferably selected from known compounds having a smectic and / or nematic and / or cholesteric phase. Suitable additional mixture components in this case are mentioned in particular in International Patent Applications PCT / EP96 / 03154 and DE-A 19748432, the descriptions of these publications being incorporated herein by reference.
The mixtures according to the invention can also be used in the area of electro-optical or all-optical elements, such as display elements, switching elements, light modulators, image processing and / or signal processing elements or generally non-linear optical components.
従って、本発明はまた、１種または２種以上の式（Ｉ）で表わされる化合物を含有するスイッチングデバイスおよび／または表示デバイス、好ましくはスメクティック液晶混合物を含有するスイッチングデバイスおよび／または表示デバイスを提供する。
アクティブマトリックス素子を備えたスイッチングデバイスおよび／または表示デバイスは、特に好ましいものとして挙げられる( 例えば、DE-A 198 22 830 参
照）。
本明細書では、本発明の技術的背景を説明するために、種々の刊行物が引用されている。これら全部の刊行物を、引用してここに組み入れる。
下記例は、本発明を説明するものであり、本発明を制限するものではない。
Accordingly, the present invention also provides a switching device and / or a display device containing one or more compounds of the formula (I), preferably a switching device and / or a display device containing a smectic liquid crystal mixture. I do.
Switching devices and / or display devices with active matrix elements are mentioned as particularly preferred (see, for example, DE-A 198 22 830).
